  • Patent number: 10340627
    Abstract: An electrical connector includes a housing, a conductive pin, a first seal, and a sealant. The housing has a bore and first and second ends exposed at different pressures when in use. The bore extends between the first and second ends. The conductive pin is arranged within the bore and configured to engage a first wire at the first end and a second wire at the second end. The first seal is arranged around the conductive pin and engaged between the conductive pin and the bore to provide seal therebetween. The sealant is provided to fill the bore between the first end and the first seal. The sealant may be an epoxy-based sealant.

  • Publication number: 20170175916
    Abstract: The control valve assembly includes a valve housing defining a bore and a valve assembly. The valve assembly includes a spool assembly disposed in the bore of the valve housing. The spool assembly includes a first spool and a second spool. The first spool has a first axial end and an oppositely disposed second axial end. The first spool is made of a first material. The first material is non-magnetic. The second spool has a first end and an oppositely disposed second end. The first end of the second spool is engaged to the second axial end of the first spool. The second spool is made of a second material. The second material is magnetic.

  • Patent number: 8770543
    Abstract: A poppet valve assembly includes a body and first and second check valves. The body includes opposing first and second axial end portions. The first end portion has a first circumferential surface, a first end surface, and a tapered surface, which seals with a main valve seat. The second axial end portion defines at least one metering slot. The body defines first and second internal passages. The first internal passage includes an opening in the first end surface, is in fluid communication with one of the metering slots, and has a first check valve seat. The second internal passage includes an opening in the first circumferential surface, is in fluid communication with one of the metering slot, and has a second check valve seat. The first and second check valves are disposed in the respective internal passages and are adapted for sealing engagement with the respective check valve seats.
